Cosine is one of the three part for trigonometry.

You have sin, cos, and tan.

You can easily do this by understanding SOH CAH TOA.

Sin = OPPO. over HYPOTENUSE
Cos = ADJACENT over HYPOTENUSE
Tan = OPPO. over ADJACENT

I hope this helps!

Answer:

By flipping the second fraction (finding its reciprocal) we change the equation mathematically. In order to maintain the equation mathematically, we must turn the division question into a multiplication question.
